Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cleaning device for a tatami surface, and is particularly configured to remove mud and dust for dyeing soil adhering to a new tatami surface during the manufacturing process of the tatami mat.
[0002]
[Prior art]
In the manufacturing process, tatami mats are woven and processed by dipping the cut grass into dyed soil and drying the grass. A blue-green tatami mat can be obtained through this mud dyeing process.
[0003]
Since this dyed soil has the effect of suppressing discoloration during the production of tatami mats, after finishing it into a tatami mat, it is removed manually with a brush, or by removing the mud on the surface of the tatami surface while rotating the brush. .
[0004]
[Problems to be solved by the invention]
A tatami mat with a new tatami mat on the tatami floor must remove the mud and dust adhering to the tatami mat before shipping. Recently, a machine that removes them by rotating a brush is used as a removal method. However, since the rotation of the brush is in one direction, the brush is wrinkled, so that the hair tip is less likely to enter the gap in the tatami mat. As a result, the mud and dust adhering to it are difficult to drop, and places where it falls and places where it does not fall, i.e., spots are generated.
[0005]
In addition, since mud and dust adhere to the brush body, if it is used for a long period of time, mud accumulates between the hairs of the brush and the hair becomes stiff and the original hair disappears. Had the problem of being unable to do so.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a cleaning apparatus for removing mud on a tatami surface, and the brush provided for cleaning inside the casing moves together with the tatami mat in the width direction of the tatami mat while rotating. To clean.
[0007]
The case and the brush reciprocate on the tatami surface, and the rotation direction is reversed in order to increase the cleaning effect at the time of forward movement and backward movement and to prevent the brush from being wrinkled. Therefore, even if the brush is used for a long period of time, the end of the hair always penetrates into the gap between the tatami surfaces, so that the durability can be dramatically improved.
[0008]
In addition, the cleaning device includes a brush cleaning plate as a brush cleaning means for removing mud and dust adhering to the brush. Mud and dust are removed by moving the casing while rotating the brush until the brush tip lightly contacts the brush cleaning plate. With this brush cleaning plate, even if the brush is used for a long period of time, mud and dust do not accumulate between the hairs, and the inherent bending of the hairs can be maintained almost permanently and their deterioration can be prevented. .
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The tatami cleaning apparatus of the present invention supports a table 5 that moves the tatami mat 17 (the surface of the tatami mat surface that is the upper surface of the tatami mat) up and down to a predetermined position, a casing 1 that runs on the tatami surface in the width direction of the tatami mat 17, and this. A moving frame 10, a brush 3 spirally attached to a shaft 2 mounted in the longitudinal direction of the tatami in the housing, and a dust collector 15 joined to the housing via a duct 4 attached to the housing 1. And a brush cleaning plate 13 for removing mud adhering to the brush, and configured to remove mud and dust adhering to the tatami surface.
[0010]
When the tatami mat 17 is placed on the table 5 and the operation switch (not shown; any switch such as a foot switch is acceptable) is turned ON, the table 5 is raised by the push-up device 11 and the tatami mat 17 is pressed against the stopper 12. The stopper 12 rises together with the tatami mat 17 and the table 5, and when it reaches a predetermined height, the sensor 18 detects the raised position of the tatami mat 17 and stops the ascent. Further, the stopper 12 has an L-shaped cross section to prevent the edges from being stained, and also serves as a cover for the tatami edges.
[0011]
As shown in the front view of FIG. 2 and FIG. 3, the brushing device includes a motor 6 provided in the housing 1, a shaft 2 that rotates via a belt 9 and pulleys 7 and 8, and a brush 3 attached to the motor 6. It is composed of
[0012]
The rotation direction of the brush 3 is a mechanism that automatically reverses when the casing 1 moves forward (right side in FIG. 2) and moves backward. By this method, the brush can clean the tatami surface without any spots and prevent the brush from being bent. Further, the peripheral speed of the brush tip is high and the brushing frequency is large.
[0013]
As shown in FIG. 4, the brush 3 of the brushing device is provided in a spiral shape perpendicular to the rotation axis and in the axial direction. The spiral pitch is dense so that the tatami surface can be cleaned without any spots.
[0014]
A housing 1 equipped with a brushing device is supported by a moving frame 10. The moving frame 10 starts moving forward when the tatami 17 is set at a predetermined position and the operation switch is turned on. When the photoelectric sensor 16 provided in the moving frame 10 detects the floor edge of the tatami mat 17, brushing is performed to the limit of the tatami edge on the side not covered with the stopper 12 by the timer control. When the time is up, the traveling motor 19 is switched from forward to backward. The timer until switching is adjustable according to the edge width.
[0015]
The brush 3 rotates in the reverse direction to the forward movement, and brushing is performed while moving backward. When the casing 1 returns to the standby position (origin position), the origin sensor (not shown) detects the operation, the operation is completed, the rotation of the brush 3 and the dust collector 15 is stopped, and the table 5 is lowered. Of course, the brushing may be reciprocated not only once but a plurality of times. Further, the operator may set the number of reciprocations.
[0016]
The cleaning device of the present invention includes a brush cleaning plate 13 having a predetermined height parallel to the axis 2 of the brush 3. (See FIGS. 2 and 5) The brushing device is moved to the brush cleaning plate 13 side, and the brush 3 is stopped by a sensor (not shown) at a position where the tip of the brush 3 contacts the brush cleaning plate 13 while rotating. Mud and dust adhering to the dust are removed and collected by the dust collector 15. This equipment cleans the tatami mat surface while keeping the brush body clean.
[0017]
It is preferable that the degree of contact of the brush 3 with the brush cleaning plate 13 can be arbitrarily adjusted by adjusting the position of the sensor. Further, the above-described cleaning operation of the brush 3 may be performed every time the brushing reciprocating motion described above is performed or every predetermined number of reciprocating motions.
[0018]
【The invention's effect】
As is clear from the description based on the above embodiment, according to the tatami cleaning apparatus of the present invention, it is possible to provide a tatami mat having a high cleanliness in a short time by automating the cleaning work before shipping in a poor working environment. it can.
